This is truly infected but purposely so with Wyeast 3278 Lambic Blend.
This photo would have been a lot more interesting if I had not tripped over a laundry basket while carrying it.
Bubbles in infected beer don't pop and they have a hazy appearance. Rafts of material seem more solid and not made up of lots of little bubbles like ordinary.
Every infection is different looking. My last lambic was much more interesting than this so I'm nervous in the opposite direction than you. I'm worried it wasn't infected enough lol.
